Flubenol - Some FAQ

Author: Aussie Chook Supplies  

The following questions have been submitted by to Aussie Chook Supplies by customers in Australia in January 2022, following the launch of Flubenol to the Australian market. As we are not qualified vets here at Aussie Chook Supplies, we then passed them onto the Australian Manufacturers of Flubenol and these are the replies recieved...  

1. Are eggs still safe to consume while worming? (If the worming treatment must be ceased for animal consumption for humans)?

Flubenol has been registered for use in Australia with a zero withholding period in eggs, I have attached the APVMA label for your reference. There is however, a 7-day withholding period for meat. I.e., all sources of medicated feed have to be withdrawn at least 7 days prior to birds being slaughtered for meat consumption.

2. What is the dosage to treat gape worm (or any other present worm) in a singular chicken? - as gape worm is in the windpipe, how is the treatment effective if it is taken though to the stomach? Should treatment involve inhaling the product? 
Flubenol is not a registered treatment for gapeworm in Australia. It is reported in the literature that flubendazole is effective against Syngamus trachea in poultry and is registered for use to treat gapeworms in chickens in New Zealand. Please see attached label for Flubenol in New Zealand. According to the NZ label for gapeworms, the dosage and route of administration is the same as per label recommendations for non-tapeworms in Australia – orally. Please also see attached label for the appropriate dosage.


3. Can I overdose a flock with the product? What is the overdose limit? 
Toxicity studies of flubendazole (the active ingredient in Flubenol) done in rats had an oral LD50 of 2560 mg/kg, which is over 4x the expected dose to treat intestinal worms other than tapeworm, and over 2x the expected dose to treat tapeworms in chickens. No toxicological information in chickens is available. Please refer to the Safety Data Sheet (SDS) for more information.

4. Frequency of worming the flock with this product? Can it be mixed with other worming products or medications?
Please consult a veterinarian for advice specific to the animals, disease status, and other medications involved.

5. Is it effective across all poultry (e.g ducks as well)? 
Flubenol is only registered for use in chickens in Australia. Please consult veterinary advice specific to the species of animals involved for alternative products or off-label recommendations.

6. Can treatment be dosed in the water?
According to the manufacturer, Flubenol is not soluble in water. Please follow label recommendations or consult veterinary advice for off-label recommendations.

7. Are there alternatives to the product? 

Flubenol is the only registered product in Australia for the treatment of tapeworms in chickens. For people seeking alternative options for the treatment of tapeworms, they should seek veterinary advice for off label recommendations. For the treatment of intestinal worms other than tapeworms, other registered worming products for use in chickens in Australia are Piperazine (for roundworms) and Levamisole (for roundworms, caecal worms and hairworms). Flubenol has been registered for use to treat the above-mentioned worms in chickens in Australia as well.

8. is it safe for humans to inhale, PPE requirements? 
Please refer to the attached Safety Data Sheet (SDS) for relevant information with regards to handling, personal protection, storage, first aid measures and other relevant information.
